Recirculating Chiller F-305, F-308, F-314Technical data sheet

The BUCHI recirculating chillers are meant to be used with laboratory equipment that requirescoolant flow such as rotary evaporators, parallel evaporators, Kjeldahl- and extraction products.The F-300 line is specifically designed for seamless integration into a BUCHI Rotavapor®R-300 system. The temperature can conveniently be set by the interface. Furthermore, it offersECO-mode, temperature lock and instant start with dynamic pressure adjustment without wait-ing until the chiller reaches its set temperature.

Explanation of terms

speed controlled Recirculating chiller is turned on/off and the temperature can be set via the interface.The actual temperature is displayed on the interface. Additional features when thesystem is operating in „controlled“ mode are listed as follows.

on/off Recirculating chiller is automatically turned on/off via the interface.

Recirculating Chiller F-305 / F-308 / F-314 featuresThe Recirculating Chillers F-305 / F-308 / F-314 offer various features when operating stand-alone or as part of a Ro-tavapor® R-300 system in conjunction with the Interface I-300 or I-300 Pro.

Feature Description With Interface

Firmware update With the BUCHI Monitor App and BUCHI BluetoothDongle, firmware updates can easily be done by the userat no costs.

Temperature setting onchiller

Set the temperature in 0.1 °C increments using thenavigation knob. Actual and set temperatures are shownon the integrated display.

Temperature lock Lock the set temperature with a push of the navigationknob to avoid unintentional changes.

Remote control withinterface

In addition to the setting of the chiller, the temperature canconveniently be set on the central interface thus showingall process parameters at a glance.

•

Remote monitoring The BUCHI Monitor App for PCs and mobile devices offerslive views and graphical displays of process parameters,as well as push notifications when an action is required, todrastically reduce the hands-on time at the instrument andfree valuable time for other tasks.

•

Dynamic operation The distillation process can be started instantly whenusing the solvent library mode. While the chiller reaches itsset temperature, the vacuum is dynamically adjusted.

•

Automatic stop The chiller can be configured to stop automatically whenthe distillation process is terminated.

•

ECO-mode Alternatively to the automatic stop the ECO-modeswitches the chiller into a stand-by mode when not in use.The temperature increases by a definable ∆T to be cooleddown to the set temperature periodically (see graphbelow).
